This invention was made with government support under Grant No. DK063368 awarded by the National Institutes of Health. The Government has certain rights in the invention.

BACKGROUND

Insulin made in the pancreas is necessary for the body to be able to use sugar as fuel. Insulin signals the intake of sugar (i.e., glucose) from the blood into cells of the body (e.g., muscles). In type I diabetes, the pancreas no longer produces insulin; so, patients with type I diabetes need to take insulin shots in order to compensate for the pancreas' inability to produce insulin. Conditions associated with type I diabetes include hypoglycemia, ketoacidosis and celiac disease. Having type I diabetes increases your risk for many serious complications including: heart disease (cardiovascular disease), blindness (retinopathy), nerve damage (neuropathy), and kidney damage (nephropathy). The insulin shortage in type I diabetes is believed to be caused by an autoimmune process in which the body's immune system destroys the β-cells in the pancreas. Thus, there is a need to identify methods of treating and preventing type I diabetes by preventing the body's immune system from destroying β-cells in the pancreas.

SUMMARY OF THE INVENTION

The invention relates to the treatment and prevention of type I diabetes. More specifically, the invention relates to compounds that treat or prevent the body's immune system from destroying β-cells (i.e., insulin-producing cells in the pancreatic islets of Langerhans) by inhibition of JNK2, selective inhibition of JNK2, or inhibition of the expression of the MAPK9 gene or gene product. In one embodiment, the present invention contemplates the diagnosis, identification, production, and use of compounds which modulate MAPK9 gene expression or the activity of the MAPK9 gene product including but not limited to, JNK2, the nucleic acid encoding MAPK9 and homologues, analogues, and deletions thereof, as well as antisense, ribozyme, triple helix, antibody, and polypeptide molecules as well as small inorganic molecules.

DETAILED DESCRIPTION OF THE INVENTION

The invention relates to the treatment and prevention of type I diabetes. More specifically, the invention relates to compounds that treat or prevent the body's immune system from destroying β-cells (i.e., insulin-producing cells in the pancreatic islets of Langerhans) by inhibition of JNK2, selective inhibition of JNK2, or inhibition of the expression of the MAPK9 gene or gene product. In one embodiment, the present invention contemplates the diagnosis, identification, production, and use of compounds which modulate MAPK9 gene expression or the activity of the MAPK9 gene product including but not limited to, JNK2, the nucleic acid encoding MAPK9 and homologues, analogues, and deletions thereof, as well as antisense, ribozyme, triple helix, antibody, and polypeptide molecules as well as small inorganic molecules.

The present invention contemplates a variety of pharmaceutical formulations and routes of administration for such compounds. The pancreas is an organ located behind the lower part of the stomach. It makes insulin and enzymes that help the body digest and use food. Spread all over the pancreas are clusters of cells called the islets of Langerhans. Islets are made up of two types of cells: alpha cells, which make glucagon, a hormone that raises the level of glucose (sugar) in the blood, and beta (β) cells, which make insulin. Failure of the insulin-producing beta cells in the pancreatic islets of Langerhans is a characteristic of type I (insulin-dependent) diabetes.

JNK1, JNK2, and JNK3 c-jun N-terminal protein kinase isoforms comprise a family of serine/threonine protein kinases of the mitogen-activating protein kinase (MAPK) group. As regulators of stress-signaling responses, JNKs play key roles in: tumor suppression, aging, neurogenesis, and immune responses. JNK2 (c-Jun N-terminal knase 2) is also called Stress-activated protein kinase 2 (SAPK2). The JNK2 gene (MAPK9) maps on chromosome 5q35 spanning 58494 base pairs (Accession No. U09759). It contains 17 confirmed introns, 14 of which are alternative. By alternative splicing, JNK2 gene encodes 12 types of transcripts that translate into 12 distinct JNK2 isoforms. The molecular weight of JNK2 is about 55 kD.

JNK1 is a protein comprising the amino acid sequence of GenBank Accession Number: L26318: Sequence Identification Number 1: (M S R S K R D N N F Y S V E I G D S T F T V L K R Y Q N L K P I G S G A Q G I V C A A Y D A I L E R N V A I K K L S R P F Q N Q T H A K R A Y R E L V L M K C V N H K NI I G L L N V F T P Q K S L E E F Q D V Y I V M E L M D A N L C Q V I Q M E L D H E R M S Y L L Y Q M L C G I K H L H S A G I I H R D L K P S N I V V K S D C T L K I L D F G L A R T A G T S F M M T P Y V V T R Y Y R A P E V I L G M G Y K E N V D L W S V G C I M G E M V C H K I L F P G R D Y I D Q W N K V I E Q L G T P C P E F M K K L Q P T V R T Y V E N R P K Y A G Y S F E K L F P D V L F P A D S E H N K L K A S Q A R D L L S K M L V I D A S K R I S V D E A L Q H P Y I N V W Y D P S E A E A P P P K I P D K Q L D E R E H T I E E W K E L I Y K E V M D L E E R T K N G V I R G Q P S P L A Q V Q Q)

JNK2 and Type I Diabetes

Mitogen-activated protein kinases (MAPKs) form a large family of serine-threonine protein kinases conserved through evolution. In mammalian cells, four distinct MAPK cascades have been identified: extracellular signal-regulated kinases (ERKs), c-Jun amino-terminal kinases (JNKs) or stress-activated protein kinases (SAPKs), p38 MAP kinase (p38) or cytokine suppressive anti-inflammatory drug binding protein, and Erk5/BMK. JNK protein kinases are activated by dual phosphorylation on Tyr and Thr. The JNK family includes JNKI (46 kDa isoform), JNK2 (55-kDa isoform), and JNK3. JNK1 and JNK2 are ubiquitously expressed, while JNK3 is largely restricted to brain, heart and testis. Ip and Davis, Curr Opin Cell Biol. 1998 April; 10(2):205-19; Sluss et al., Mol Cell Biol. 1994 December; 14(12):8376-84. In addition to stress such as UV exposure, the INK family is activated by cytokines and TNF-α.

Recently, it has been suggested that JNK1, but not JNK2, is implicated in obesity and insulin resistance associated with type II diabetes. International publication PCT (WO 02/085396), Lee et al., c-Jun N-terminal kinase (JNK) mediates feedback inhibition of the insulin signaling cascade. J Biol Chem 278, 2896-902 (2003), and Aguirre et al., The c-Jun NH(2)-terminal kinase promotes insulin resistance during association with insulin receptor substrate-1 and phosphorylation of Ser(307). J Biol Chem 275, 9047-54 (2000).

JNKs take part in the regulation of CD4+ T cell differentiation. Recently studies suggest the cooperation of CD4+ and CD8+ T cells for islet infiltration and destruction of β-cells. The cytokine environment enables the differentiation of CD4+ T cells to two different phenotypes: 1) Th1 cells which produce interleukin-2 (IL-2) and interferon-γ (IFN-γ) inducing a cellular immune response or 2) Th2 cells that secrete IL-4, IL-5, and IL-10 which support humoral immunity and down-regulate the inflammatory actions of Th1 cells. Benign insulitis is associated with differentiation of CD+ T cells in a phenotype of Th2 cells, whereas destructive insulitis appears to be associated with Th1 cells. Pro-inflammatory cytokines produced by islet infiltrating immune cells act as effector molecules, and IL-1β in combination with IFN-γ and TNF-α triggers apoptosis of the β-cells.

The applicant has discovered that JNK2 plays role in type I (insulin-dependent) diabetes that is caused by autoimmune destruction of β-cells. Studies of non-obese diabetic (NOD) mice demonstrated that disruption of the MAPK9 gene (which encodes the JNK2 protein kinase) decreased destructive insulitis and reduced disease progression to type I diabetes. CD4+ T cells from JNK2-deficient NOD mice produced less IFN-γ, and significantly increased amounts of IL-4 and IL-5, indicating polarization towards the Th2 phenotype. This role of JNK2 to control the Th1/Th2 balance of the immune response motivated the applicant to use JNK2 inhibitors to protect against type I autoimmune diabetes.

The applicants discovered reduced insulitis and reduced progression to type I diabetes in NOD/Mapk9−/− mice. The transition from non-pathogenic insulitis to type I diabetes correlates with the change from a predominance of Th2 to Th1 cytokines in the islets. A Th1 (IFN-γ) environment accelerates the recruitment of islet-specific CD4+ T cells and also accelerates the onset of type I diabetes. In contrast, a Th2 pancreatic environment appears to protect against autoimmune diabetes. Thus, administration of IL-4 systemically or expression of IL-4 in NOD mice in vivo interferes with the islet infiltration by T cells and prevents Th1-mediated destructive insulitis and type I diabetes. The observation that JNK2-deficiency causes selective polarization of CD4+ T cells to the Th2 phenotype with increased IL-4 expression can lead to creation of a Th2 pancreatic environment that protects against autoimmune diabetes. Thus, one embodiment of the current invention is the treatment and prevention of type I diabetes by administering to a subject an inhibitor of JNK2. In further embodiments, the JNK2 inhibitor selectively inhibits JNK2.

Inappropriate activation of T cells initiates many autoimmune diseases. Although, the applicant does not desire the invention to be limited to any particular mechanism, JNK2 inhibitors may play several roles in preventing type I diabetes. JNK2 inhibitors may play a suppressive role in autoimmune disease by causing a negative selection of autoreactive T cells in the thymus. In type I diabetes, JNK2 inhibitors may prevent beta-cell apoptosis caused by cytokines and oxidative stress caused by reactive oxygen species and nitric oxide. Furthermore, JNK2 inhibitors may prevent the production of macrophage-derived cytokines, including TNF-α, contributing to the development of destructive insulitis and diabetes. It is possible that JNK2 inhibitors act in multiple ways as those mentioned or those not mentioned.

JNK2 Inhibitors

The present invention is direct to methods useful for treating or preventing type I diabetes in a subject, comprising administering an effective amount of a JNK2 inhibitor or selective JNK2 inhibitor. Illustrative JNK2 inhibitors and JNK2 selective inhibitors are set forth below.

Antisense oligonucleotides of JNK2 have been described in U.S. Pat. Nos. 6,221,850 and 6,133,246, which are hereby incorporated by reference. Oligonucleotides that are specifically hybridizable with nucleic acids encoding JNK2 are JNK2 inhibitors. Embodiments include oligonucleotides comprising up to 30 nucleotides (typically between 15 and 25 nucleotides) in length wherein said oligonucleotides have a sequence that specifically binds to nucleic acids encoding JNK2 (e.g. human MAPK9 gene, GenBank Accession number NC 000005 and any corresponding mRNA). Further illustrative embodiments can be found in the corresponding patents provided above. JNK-interacting protein-1 (JIP-1) was first identified as a direct binding partner for JNK1 in yeast two-hybrid analysis. The specificity of interactions was underlined by JIP-1 interacting with JNK1, JNK2, and JNK3, but not ERK or p38 MAPKs, and failing to alter the activity of these two closely related MAPKs. Furthermore, JNKs bound to JIP-1 with greater affinity than its transcription factor substrates, c-Jun and activating transcription factor-2 (ATF2). A number of amino acid sequences based on the binding domain of JIP-1, JIP-2, and c-Jun have been disclosed as JNK inhibitors including those disclosed in WO 03/103698, U.S. Pat. No. 6,780,970, and U.S. Patent Application Publication 2002/0119135, all of which or any present or future corresponding U.S. application or patent are hereby incorporated by reference. Examples of JNK2 inhibitor peptides include a peptide which includes (in whole or in part) the sequence NH₂-DTYRPKRPTTLNLFPQVPRSQDT-COOH [SEQ ID NO:3]. In another embodiment, the peptide includes the sequence NH₂-EEPHKHRPTTLRLTTLGAQDS-COOH [SEQ ID NO:4]. In another embodiment, the peptide includes the sequence NH2-FLNLTTPRKPR-COOH [SEQ ID NO:5]. In another embodiment the peptide includes the sequence NH₂-FLNLTTPRKPRYTDGSGTGPG-COOH [SEQ ID NO:6]. Further illustrative embodiments can be found in the identified references.

The JNK2 inhibitor peptides can be polymers of L-amino acids, D-amino acids, or a combination of both. For example, in various embodiments, the peptides are D retro-inverso peptides. The term “retro-inverso isomer” refers to an isomer of a linear peptide in which the direction of the sequence is reversed and the chirality of each amino acid residue is inverted. The net result of combining D-enantiomers and reverse synthesis is that the positions of carbonyl and amino groups in each amide bond are exchanged, while the position of the side-chain groups at each alpha carbon is preserved. Unless specifically stated otherwise, it is presumed that any given L-amino acid sequence of the invention may be made into a D retro-inverso peptide by synthesizing a reverse of the sequence for the corresponding native L-amino acid sequence.

The embodiments of the current invention are not limited to compounds with the structures provide. JNK2 inhibitors and selective JNK2 inhibitors can be made using organic synthesis techniques known to those skilled in the art, as well as by the methods described in the respective identified references.

JNK2 Assays

Proteins can be purified by expressing the amino acid sequence (i.e., JNK2) in a host, such as E. coli. The protein may be expressed in combination with a second amino acid sequence (fusion-proteins) that has properties preferential for purification. For example, The Glutathione S-transferase (GST) gene fusion system is an integrated system for the expression, purification and detection of fusion proteins produced in bacterial, yeast, mammalian and insect cells.

The sequence encoding the GST protein is incorporated into an expression vector, generally upstream of the multi-cloning site. The sequence encoding the protein of interest is then cloned into this vector. Induction of the vector results in expression of a fusion protein—the protein of interest fused to the GST protein. The fusion protein can then be released from the cells and purified.

Purification of the fusion protein is facilitated by the affinity of the GST protein for glutathione residues. Glutathione residues are coupled to a resin and the expressed protein product is brought into contact with the resin. The fusion protein will bind to the glutathione-resin complex and all other non-specific proteins can be washed off. The fusion protein can then be released from the resin using a mild elution buffer that is of low pH. Similarly, poly-histidine sequences (his-tags) can be used.

It is possible to remove the GST or his-tag from the protein of interest by using a number of different enzymes (thrombin, factor X), which cleave specific sites between the GST or his-tag and the protein of interest. Fusion proteins can also be detected easily, with a number of antibodies now available on the market.

There are many well-known methods to one skilled in the art for determining the binding of one protein to another. One or more of the following methods and other methods well-known to those skilled in the art can be used to determine whether a compound is an inhibitor JNK2 or selective inhibitor of JNK2.

For example, to 10 μL of 5-amino-anthra(9,1-cd)isothiazol-6-one in 20% DMSO/80% dilution buffer containing of 20 mM HEPES (pH 7.6), 0.1 mM EDTA, 2.5 mM magnesium chloride, 0.004% Triton×100, 2 μg/mL leupeptin, 20 mM β-glycerolphosphate, 0.1 mM sodium vanadate, and 2 mM DTT in water is added 30 μL of 50-200 ng His6-JNK2 in the same dilution buffer. The mixture is pre-incubated for 30 minutes at room temperature. Sixty μL of 10 μg GST-c-Jun(1-79) in assay buffer consisting of 20 mM HEPES (pH 7.6), 50 mM sodium chloride, 0.1 mM EDTA, 24 mM magnesium chloride, 1 mM DTT, 25 mM PNPP, 0.05% Triton×100, 11 μM ATP, and 0.5 μCi γ-32P ATP in water is added and the reaction is allowed to proceed for 1 hour at room temperature. The c-Jun phosphorylation is terminated by addition of 150 μL of 12.5% trichloroacetic acid. After 30 minutes, the precipitate is harvested onto a filter plate, diluted with 50 μL of the scintillation fluid and quantified by a counter. The IC₅₀ values are calculated as the concentration of 5-amino-anthra(9,1-cd)isothiazol-6-one at which the c-Jun phosphorylation is reduced to 50% of the control value. Compounds that inhibit JNK2 preferably have an IC₅₀ value ranging 0.01-10 μM in this assay. 5-Amino-anthra(9,1-cd)isothiazol-6-one has an IC₅₀ according to this assay of 1 μM for JNK2 and 400 nM for JNK3. The measured IC₅₀ value for 5-amino-anthra(9,1-cd)isothiazol-6-one, as measured by the above assay, however, shows some variability due to the limited solubility of 5-amino-anthra(9,1-cd)isothiazol-6-one in aqueous media. Despite the variability, however, the assay consistently does show that 5-amino-anthra(9,1-cd)isothiazol-6-one selectively inhibits JNK2. This assay demonstrates that 5-amino-anthra(9,1-cd)isothiazol-6-one, an illustrative JNK2 inhibitor, inhibits JNK2 selectively and, accordingly, is useful for treating or preventing type I diabetes.

In other examples, following pretreatment with JNK2 inhibitor (63-1700 nM in Buffer B (20 mM HEPES, 20 mM MgCl₂, 20 mM β-glycerophosphate, pH 7.6, containing 500 μm dithiothreitol, 100 μm sodium orthovanadate), JNK activity is assayed by incubation in Buffer B supplemented with 20 μm ATP, 1 μCi of [γ-³²P]ATP, and a protein substrate (10 μg of either GST-c-Jun, GST-Elk, or GST-ATF2). The reaction is performed for 30 min at 30° C., and then the phosphorylated substrate was separated by SDS-PAGE, visualized by autoradiography, and quantitated by Cerenkov counting.

C-Jun Reporter Assays

Detection of JNK2 inhibition is also described in United States Patent Application Publication US 2004/0248886 A1, hereby incorporated by reference. The phosphorylation of c-jun by JNK2 is followed by monitoring the incorporation of ³³P into c-jun following the protocol below. The inhibitory activity of the JNK2 inhibitors, towards c-jun phosphorylation through JNK2, is determined by calculating phosphorylation activity in the presence or absence of JNK2 inhibitor.

JNK2 assays can be performed in 96 well MTT plates: incubation of 0.5 μm of recombinant, pre-activated GST-JNK2 with 1 μg of recombinant, biotinylated GST-c-Jun and 2 μM ³³γ-ATP (2 nCi/μL), in the presence or absence of JNK2 inhibitor and in a reaction volume of 50 μL, containing 50 mM Tris-HCl, pH 8.0; 10 mM MgCl₂; 1 mM Dithiothreitol, and 100 μm Na₃VO₄. The incubation is performed for 120 min. at R. T and stopped upon addition of 200 μL of a solution containing 250 μg of Streptavidine-coated SPA beads (Amershain, Inc.), 5 mM EDTA, 0.1% TritonX-100 and 50 μm ATP, in phosphate saline buffer.

After incubation for 60 minutes at RT, beads are sedimented by centrifugation, resuspended in 200 μL of PBS containing 5 mM EDTA, 0.1% Triton X-100 and 50 μM ATP and the radioactivity measured in a scintillation beta counter, following sedimentation of the beads as described above. By replacing biotinylated GST-c Jun with biotinylated GST-₁ATF₂ or biotinylated myelin basic protein, this assay can be used to measure inhibition of preactivated p38 and ERK MAP Kinases, respectively. The JNK2 inhibitors display an inhibition (IC₅₀) with regard to JNK2 of less than 10 μM, preferably less than 1 μM and more preferred less than 0.25 μM.

The phosphorylation of the transcriptional factor, c-jun, by JNK2 in the MAP kinase signal transduction pathway can be followed via a trans-reporting system such as the commercially available PathDetect as provided in Xu, L. et al., Assess the in-vivo activation of signal transduction pathways with Pathdetect reporting systems, Strategies 2001, 14 (1): 17-19.

A trans-reporting system allows one to follow, via Luciferase activity, the activation status of a fusion trans-activator protein. The trans-activator protein consists of the activation domain of the transcriptional factor of interest (c-jun) fused with a yeast transcriptional activator, GAL4 DNA binding domain (dbd). The GAL4 dbd has the advantage that no known mammalian transcriptional factors bind to it and therefore the background noise of the assay is very low.

In the present case, Hela luciferase reporter-c-Jun (HLR-c-Jun) cell lines that constitutively express GAL4-cJun may be used. Recombinant JNK2 and substrates (c-Jun-(1-135), Elk-(307-428), or ATF2-(19-96)) may be produced in Escherichia coli as GST fusion proteins. For JNK2, the GST portion of the fusion protein may be removed by overnight cleavage with thrombin (3 units) in Thrombin Cleavage buffer (50 mM Tris, pH 8.0, 150 mM NaCl, 5 mM MgCl₂, 2.5 mM CaCl₂, and 1 mM dithiothreitol)

Once, JNK is activated it can induce the phosphorylation of the c-jun domain of the fusion trans-activator protein (GAL4 dbd-cjun) which forms a dimer. The dimer is then is able to bind to a GAL4 upstream activating sequence (GAL4 UAS) of the reporter that activates Luciferase expression. Luciferase expression is detected by luminescence using a simple assay such as Dual-Luciferase Reporter Assay System in which Renilla is used as a “control reporter”. Inhibition of JNK is observed as a decrease in Luciferase expression and detected by a decrease in luminescence. U.S. Patent Number U.S. Pat. No. 5,744,320, hereby incorporated by reference, describes a Dual-Luciferase Reporter Assay System.

LPS Induced Endotoxin Shock in Mice

Endotoxins are the lipopolysaccharides (LPS) constituents of the outer membrane of Gram-negative bacteria. Response to LPS has been shown to involve the activation of different cell populations and to lead to the expression of various inflammatory cytokines that include tumor necrosis factor-alpha (TNF-α) and interferon γ (IFN-γ). As LPS is known to stimulate the activation of various MAP kinase pathways, including MK, the ability of JNK inhibitors can be tested after the JNK signaling pathway has been switched on by a LPS challenge.

The activity as JNK inhibitors of compounds of formula may be assessed after a LPS challenge using the following protocol: LPS(S. abortus-Galanos Lab-) is injected (200 μg/kg, i.v.) to Male C57BL/6 mice to induce endotoxin shock. Compounds (0.1, 1, 10 mg/kg) or NaCl (200 μM) are injected intravenously (10 mL/kg) 15 min before the LPS challenge. Heparinized blood was obtained from the orbital sinus at different time points after the LPS challenge, and the blood was centrifuged at 9'000 rpm for 10 mM at 4° C. to collect supernatant. Measurement of cytokines production such as TNF-α and IFN-γ by mouse is performed with an ELISA kit such as Duoset DY410 for TNF-α and DY 485 for IFN-γ. Other ELISA assays can be used.

Surface Plasmon Resonance

Real time kinetic studies of the interactions between recombinant JNK proteins (JNK2, JNK3, and kinase-inactive JNK3) and peptide may be performed on a BIAcore 2000 biosensor. The running and sample dilution buffer is 10 mM HEPES, pH 7.4, 150 mM NaCl, 3.4 mM EDTA, 0.005% (v/v) Tween 20. The biotinylated peptide may immobilized onto 3 flow cells of each 4-flow cell SA-biosensor chip to achieve ˜20, 40, and 80 resonance units (RU). The remaining blank flow cell on each chip measured background interactions.

The binding of proteins to the immobilized peptides is recorded as RU in real time to provide a sensorgram. Binding profiles are created by injecting 10 μM JNK2, JNK3, and kinase-inactive JNK3 (JNK3 (kin⁻)) at a flow rate of 20 μl/min. GST-c-Jun-(1-135), GST-Elk-(307-428), and GST-ATF2-(19-96) are injected at 5 μm concentration to approximate concentrations present during standard in vitro kinase assays.

Pharmaceutical Compositions

The compositions comprising a JNK2 inhibitor include bulk-drug compositions useful in the manufacture of pharmaceutical compositions (e.g., impure or non-sterile compositions) and pharmaceutical compositions (i.e., compositions that are suitable for administration to a patient) that can be used in the preparation of unit dosage forms. Such compositions optionally comprise a prophylactically or therapeutically effective amount of a prophylactic and/or therapeutic agent disclosed herein or a combination of those agents and a pharmaceutically acceptable carrier. Preferably, compositions of the invention comprise a prophylactically or therapeutically effective amount of JNK2 inhibitor and another therapeutic or prophylactic agent, and a pharmaceutically acceptable carrier.

In a specific embodiment, the term “pharmaceutically acceptable” means approved by a regulatory agency of the Federal or a state government or listed in the U.S. Pharmacopeia or other generally recognized pharmacopeia for use in animals, and more particularly in humans. The term “carrier” refers to a diluent, adjuvant, excipient, or vehicle with which a JNK2 inhibitor is administered. Such pharmaceutical vehicles can be liquids, such as water and oils, including those of petroleum, animal, vegetable or synthetic origin, such as peanut oil, soybean oil, mineral oil, sesame oil and the like. The pharmaceutical vehicles can be saline, gum acacia, gelatin, starch paste, talc, keratin, colloidal silica, urea, and the like. In addition, auxiliary, stabilizing, thickening, lubricating and coloring agents can be used. When administered to a patient, the pharmaceutically acceptable vehicles are preferably sterile. Water can be the vehicle when the JNK2 inhibitor is administered intravenously. Saline solutions and aqueous dextrose and glycerol solutions can also be employed as liquid vehicles, particularly for injectable solutions. Suitable pharmaceutical vehicles also include excipients such as starch, glucose, lactose, sucrose, gelatin, malt, rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate, talc, sodium chloride, dried skim milk, glycerol, propyleneglycol, water, ethanol and the like. The present compositions, if desired, can also contain minor amounts of wetting or emulsifying agents, or pH buffering agents.

The present compositions can take the form of solutions, suspensions, emulsion, tablets, pills, pellets, capsules, capsules containing liquids, powders, sustained-release formulations, suppositories, emulsions, aerosols, sprays, suspensions, or any other form suitable for use. In one embodiment, the pharmaceutically acceptable vehicle is a capsule (see e.g., U.S. Pat. No. 5,698,155).

In a preferred embodiment, the JNK2 inhibitor and optionally a therapeutic or prophylactic agent are formulated in accordance with routine procedures as pharmaceutical compositions adapted for intravenous administration to human beings. Typically, JNK2 inhibitors for intravenous administration are solutions in sterile isotonic aqueous buffer. Where necessary, the compositions can also include a solubilizing agent. Compositions for intravenous administration can optionally include a local anesthetic such as lignocaine to ease pain at the site of the injection. Generally, the ingredients are supplied either separately or mixed together in unit dosage form, for example, as a dry lyophilized powder or water free concentrate in a hermetically sealed container such as an ampoule or sachette indicating the quantity of active agent. Where the JNK2 inhibitor is to be administered by infusion, it can be dispensed, for example, with an infusion bottle containing sterile pharmaceutical grade water or saline. Where the JNK2 inhibitor is administered by injection, an ampoule of sterile water for injection or saline can be provided so that the ingredients can be mixed prior to administration.

Compositions for oral delivery can be in the form of tablets, lozenges, aqueous or oily suspensions, granules, powders, emulsions, capsules, syrups, or elixirs, for example. Orally administered compositions can contain one or more optional agents, for example, sweetening agents such as fructose, aspartame or saccharin; flavoring agents such as peppermint, oil of wintergreen, or cherry; coloring agents; and preserving agents, to provide a pharmaceutically palatable preparation. Moreover, where in tablet or pill form, the compositions can be coated to delay disintegration and absorption in the gastrointestinal tract thereby providing a sustained action over an extended period of time. Selectively permeable membranes surrounding an osmotically active driving compound are also suitable for an orally administered JNK2 inhibitor. In these later platforms, fluid from the environment surrounding the capsule is imbibed by the driving compound, which swells to displace the agent or agent composition through an aperture. These delivery platforms can provide an essentially zero order delivery profile as opposed to the spiked profiles of immediate release formulations. A time delay material such as glycerol monostearate or glycerol stearate can also be used. Oral compositions can include standard vehicles such as mannitol, lactose, starch, magnesium stearate, sodium saccharine, cellulose, magnesium carbonate, and the like. Such vehicles are preferably of pharmaceutical grade.

Further, the effect of the JNK2 inhibitor can be delayed or prolonged by proper formulation. For example, a slowly soluble pellet of the JNK2 inhibitor can be prepared and incorporated in a tablet or capsule. The technique can be improved by making pellets of several different dissolution rates and filling capsules with a mixture of the pellets. Tablets or capsules can be coated with a film that resists dissolution for a predictable period of time. Even the parenteral preparations can be made long-acting, by dissolving or suspending the compound in oily or emulsified vehicles which allow it to disperse only slowly in the serum.

Formulations

Pharmaceutical compositions for use in accordance with the present invention can be formulated in conventional manner using one or more physiologically acceptable carriers or excipients.

Thus, the JNK2 inhibitor and optionally the therapeutic or prophylactic agent and their physiologically acceptable salts and solvates can be formulated into pharmaceutical compositions for administration by inhalation or insufflation (either through the mouth or the nose) or oral, parenteral or mucosol (such as buccal, vaginal, rectal, sublingual) administration. In one embodiment, local or systemic parenteral administration is used.

For oral administration, the pharmaceutical compositions can take the form of, for example, tablets or capsules prepared by conventional means with pharmaceutically acceptable excipients such as binding agents (e.g., pregelatinised maize starch, polyvinylpyrrolidone or hydroxypropyl methylcellulose); fillers (e.g., lactose, microcrystalline cellulose or calcium hydrogen phosphate); lubricants (e.g., magnesium stearate, talc or silica); disintegrants (e.g., potato starch or sodium starch glycolate); or wetting agents (e.g., sodium lauryl sulphate). The tablets can be coated by methods well known in the art. Liquid preparations for oral administration can take the form of, for example, solutions, syrups or suspensions, or they can be presented as a dry product for constitution with water or other suitable vehicle before use. Such liquid preparations can be prepared by conventional means with pharmaceutically acceptable additives such as suspending agents (e.g., sorbitol syrup, cellulose derivatives or hydrogenated edible fats); emulsifying agents (e.g., lecithin or acacia); non-aqueous vehicles (e.g., almond oil, oily esters, ethyl alcohol or fractionated vegetable oils); and preservatives (e.g., methyl or propyl-p-hydroxybenzoates or sorbic acid). The preparations can also contain buffer salts, flavoring, coloring and sweetening agents as appropriate.

Preparations for oral administration can be suitably formulated to give controlled release of the active compound.

For buccal administration the pharmaceutical compositions can take the form of tablets or lozenges formulated in conventional manner.

For administration by inhalation, the pharmaceutical compositions for use according to the present invention are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebulizer, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol the dosage unit can be determined by providing a valve to deliver a metered amount. Capsules and cartridges of e.g., gelatin for use in an inhaler or insufflator can be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch.

The pharmaceutical compositions can be formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion. Formulations for injection can be presented in unit dosage form, e.g., in ampoules or in multi-dose containers, with an added preservative. The pharmaceutical compositions can take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and can contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Alternatively, the active ingredient can be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.

The pharmaceutical compositions can also be formulated in rectal compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter or other glycerides.

In addition to the formulations described previously, the pharmaceutical compositions can also be formulated as a depot preparation. Such long acting formulations can be administered by implantation (for example subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the pharmaceutical compositions can be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.

The invention also provides that a pharmaceutical composition is packaged in a hermetically sealed container such as an ampoule or sachette indicating the quantity. In one embodiment, the pharmaceutical composition is supplied as a dry sterilized lyophilized powder or water free concentrate in a hermetically sealed container and can be reconstituted, e.g., with water or saline to the appropriate concentration for administration to a patient.

In other embodiments of the invention, radiation therapy agents such as radioactive isotopes can be given orally as liquids in capsules or as a drink. Radioactive isotopes can also be formulated for intravenous injection. The skilled oncologist can determine the preferred formulation and route of administration.

The pharmaceutical compositions can, if desired, be presented in a pack or dispenser device that can contain one or more unit dosage forms containing the active ingredient. The pack can for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device can be accompanied by instructions for administration.

In certain preferred embodiments, the pack or dispenser contains one or more unit dosage forms containing no more than the recommended dosage formulation as determined in the Physician's Desk Reference (56^(th) ed. 2002, herein incorporated by reference in its entirety).

Routes of Administration

Methods of administering a JNK2 inhibitor and optionally a therapeutic or prophylactic agent include, but are not limited to, parenteral administration (e.g., intradermal, intramuscular, intraperitoneal, intravenous and subcutaneous), epidural, and mucosal (e.g., intranasal, rectal, vaginal, sublingual, buccal or oral routes). In a specific embodiment, the JNK2 inhibitor and optionally the prophylactic or therapeutic agents are administered intramuscularly, intravenously, or subcutaneously. The JNK2 inhibitor and optionally the prophylactic or therapeutic agent can also be administered by infusion or bolus injection and can be administered together with other biologically active agents. Administration can be local or systemic. The JNK2 inhibitor and optionally the prophylactic or therapeutic agent and their physiologically acceptable salts and solvates can also be administered by inhalation or insufflation (either through the mouth or the nose). In a preferred embodiment, local or systemic parenteral administration is used.

In specific embodiments, it can be desirable to administer the JNK2 inhibitor locally to the area in need of treatment. This can be achieved, for example, and not by way of limitation, by local infusion during surgery, topical application, e.g., in conjunction with a wound dressing after surgery, by injection, by means of a catheter, by means of a suppository, or by means of an implant, said implant being of a porous, non-porous, or gelatinous material, including membranes, such as silastic membranes, or fibers. In one embodiment, administration can be by direct injection at the site (or former site) of an atherosclerotic plaque tissue.

Pulmonary administration can also be employed, e.g., by use of an inhaler or nebulizer, and formulation with an aerosolizing agent, or via perfusion in a fluorocarbon or synthetic pulmonary surfactant. In certain embodiments, the JNK2 inhibitor can be formulated as a suppository, with traditional binders and vehicles such as triglycerides.

In another embodiment, the JNK2 inhibitor can be delivered in a vesicle, in particular a liposome.

In yet another embodiment, the JNK2 inhibitor can be delivered in a controlled release system. In one embodiment, a pump can be used. In another embodiment, polymeric materials can be used.

Dosages

The amount of the JNK2 inhibitor that is effective in the treatment or prevention of type I diabetes can be determined by standard research techniques. For example, the dosage of the JNK2 inhibitor which will be effective in the treatment or prevention of type I diabetes can be determined by administering the JNK2 inhibitor to an animal in a model such as, e.g., the animal models known to those skilled in the art. In addition, in vitro assays can optionally be employed to help identify optimal dosage ranges.

Selection of a particular effective dose can be determined (e.g., via clinical trials) by a skilled artisan based upon the consideration of several factors which will be known to one skilled in the art. Such factors include the disease to be treated or prevented, the symptoms involved, the patient's body mass, the patient's immune status and other factors known by the skilled artisan.

The precise dose to be employed in the formulation will also depend on the route of administration, and the seriousness of the disease-related wasting, and should be decided according to the judgment of the practitioner and each patient's circumstances. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.

The dose of a JNK2 inhibitor to be administered to a patient, such as a human, is rather widely variable and can be subject to independent judgment. It is often practical to administer the daily dose of a JNK2 inhibitor at various hours of the day. However, in any given case, the amount of a JNK2 inhibitor administered will depend on such factors as the solubility of the active component, the formulation used, patient condition (such as weight), and/or the route of administration.

The general range of effective amounts of the JNK2 inhibitor alone or in combination with the prophylactic or therapeutic agent(s) are from about 0.001 mg/day to about 1000 mg/day, more preferably from about 0.001 mg/day to 750 mg/day, more preferably from about 0.001 mg/day to 500 mg/day, more preferably from about 0.001 mg/day to 250 mg/day, more preferably from about 0.001 mg/day to 100 mg/day, more preferably from about 0.001 mg/day to 75 mg/day, more preferably from about 0.001 mg/day to 50 mg/day, more preferably from about 0.001 mg/day to 25 mg/day, more preferably from about 0.001 mg/day to 10 mg/day, more preferably from about 0.001 mg/day to 1 mg/day. Of course, it is often practical to administer the daily dose of compound in portions, at various hours of the day. However, in any given case, the amount of compound administered will depend on such factors as the solubility of the active component, the formulation used, subject condition (such as weight), and/or the route of administration.

For antibodies, the dosage administered to a patient is typically 0.1 mg/kg to 100 mg/kg of the patient's body weight. Preferably, the dosage administered to a patient is between 0.1 mg/kg and 20 mg/kg of the patient's body weight, more preferably 1 mg/kg to 10 mg/kg of the patient's body weight. Generally, human and humanized antibodies have a longer half-life within the human body than antibodies from other species due to the immune response to the foreign polypeptides. Thus, lower dosages of human antibodies and less frequent administration is often possible.

The invention provides for any method of administrating lower doses of known agents (e.g., insulin) than previously thought to be useful for the prevention or treatment of type I diabetes.

Example 1

Spontaneous diabetes is decreased in JNK2-deficient mice. We used the non-obese diabetic (NOD) mouse model of autoimmune diabetes as disclosed in Delovitch & Singh, The non-obese diabetic mouse as a model of autoimmune diabetes: immune dysregulation gets the NOD. Immunity 7, 727-38 (1997). NOD and NOD/Scid mice were obtained from The Jackson Laboratory (Bar Harbor, Me.). Mapk9−/− mice (Yang, D. D. et al. Differentiation of CD4+ T cells to Th1 cells requires MAP kinase JNK2. Immunity 9, 575-85 (1998)) were back-crossed with NOD mice for 6 generations and Jnk2−/+ mice that are homozygous for the 15 Idd NOD alleles were identified by PCR genotyping, as described previously (Mora et al., Role of L-selectin in the development of autoimmune diabetes in non-obese diabetic mice. Int Immunol 16, 257-64 (2004)). These NOD/Mapk9−/+mice were back-crossed for an additional four generations onto the NOD background. NOD/Mapk9−/− mice were obtained by crossing NOD/Mapk9−/+ mice. The Mapk9 genotype was examined by PCR analysis. Blood glucose levels were monitored weekly with a Dex-Glucometer (Bayer). Animals with a blood glucose level higher than 200 mg/dl for 2 consecutive weeks were considered diabetic.

The presence of hyperglycemia (blood glucose >200 mg/dl) was examined in a cohort of 32 NOD mice and 28 female NOD/Mapk9−/− mice. The data in FIG. 1 is presented as the % of mice with hyperglycemia. Comparison of the spontaneous incidence of disease in female NOD and NOD/Mapk9−/− mice indicated that JNK2-deficiency decreases the cumulative incidence of diabetes.

Example 2

JNK2-defiency causes reduced insulitis in NOD mice. We performed histological analysis of the pancreas. At 13 weeks of age, control NOD mice exhibited severe islet infiltration with less than 20% normal islets and greater than 50% of the islets showing invasive and destructive insulitis. In contrast, more than 70% of the islets in JNK2-deficient mice were not infiltrated and the residual 30% showed mostly peri-insulitis (FIG. 2 a,b). At 30 weeks of age, all the islets of NOD mice showed severe destructive insulitis, but normal un-infiltrated islets were detected in JNK2-deficient NOD mice. Control studies demonstrated that the extent of islet infiltration in JNK1-deficient (Mapk8−/−) NOD mice was similar to wild type NOD mice, indicating a selective role for JNK2 in the regulation of islet infiltration in NOD mice.

Example 3

JNK2-deficiency causes reduced diabetes in adoptive transfer studies. Autoimmune diabetes can be adoptively transferred to euglycemic recipients by injection of splenic T cells. In order to examine the diabetogenic potential of T cells from JNK2-deficient mice, T cells from young (13 week old) non-diabetic NOD and NOD/Mapk9−/− mice were transferred into NOD/Scid recipients. NOD/Scid mice were injected intravenously with 2×10⁷ total splenocytes and were monitored (14 weeks) for diabetes. NOD mice (7 weeks old males) were irradiated (725 rad) one day prior to adoptive transfer of 2×10⁷ total splenocytes from recently diagnosed diabetic donors by intravenous injection; the mice were monitored (8 weeks) for diabetes. The incidence of diabetes was significantly reduced if recipient mice received splenic T cells from JNK2-deficient donors compared to control NOD donors (FIG. 3 a). This observation indicates that the generation of beta-cell specific diabetogenic T cells may be impaired in JNK2-deficient mice.

Example 4

Analysis of the distribution of T cell populations and their activation markers in lymph nodes and spleen showed no difference between non-diabetic NOD and NOD/Mapk9−/− mice. The presence of T cells in infiltrated islets was examined by immunohistochemistry on frozen pancreatic sections. Pancreata were fixed in 10% formalin, embedded in paraffin, sectioned and stained with hematoxylin-eosin. Immunohistochemistry was performed using tissue embedded in Tissue-Tek OCT and frozen in 2-methylbutane. 5 μm sections were stained with FITC-conjugated antibodies to CD4 and CD8 (PharMingen) and mounted in Vectashield with DAPI (Vector Laboratories).

Although the number of infiltrated islets in NOD mice was greater than the number of infiltrated islets in NOD/Mapk9−/− mice (FIG. 2), the percentage of CD4+ and CD8+ T cells within the infiltrated islets was similar in NOD and NOD/Mapk9−/− mice (FIG. 4 a). A Th1 (IFN-gamma) environment accelerates the recruitment of islet-specific CD4+ T cells and also accelerates the onset of diabetes, while a Th2 environment protects against autoimmune diabetes. We therefore examined whether JNK2-deficiency in NOD CD4+ T cells could promote the differentiation of these cells into Th2 effector cells. CD4+ T cells were isolated from non-diabetic 8-week-old NOD and JNK2-deficient NOD mice and activated with immobilized anti-CD3 monoclonal antibody (mAb) and soluble anti-CD28 mAb in the presence of IL-4 (to promote Th2 differentiation) or IL-12 (to promoteTh1 differentiation). After 4 days of differentiation, the cells were washed and re-restimulated with immobilized anti-CD3 mAb. Culture supernatants were then harvested 24 h later for analysis of cytokine production. Although WN-gamma secretion by Th1 cells was not significantly affected in JNK2-deficient mice (FIG. 4 a), the production of IL-4 by Th2 cells and Th1 cells was substantially increased in these mice compared with wild-type mice (FIG. 4 a). Similarly, the secretion of IL-5, another Th2 cytokine, was also augmented in Th2 and Th1 cells from JNK2-deficient mice (FIG. 4 b).

Example 5

To demonstrate that JNK2-deficiency promoted the production of Th2 cytokines, we examined the cytokine profile of non-polarized effector (Th0) cells differentiated with anti-CD3 and anti-CD28 mAbs in the absence of exogenous cytokines. Although IL-4 secretion by wild-type NOD Th0 cells was not detected, high levels of IL-4 were produced by JNK2-deficient NOD Th0 cells (FIG. 4A). Furthermore, the amount of IL-5 secreted by JNK2-deficient NOD Th0 cells was similar to the high level produced by Th2 cells, but no IL-5 production by NOD Th0 cells was detected. In addition, the expression of IFN-gamma by Th0 cells from JNK2-deficient mice was greatly reduced (FIG. 4 b). To test whether this phenotype was due to an impaired differentiation or to an impaired activation of effector cells, we examined cytokine production during the differentiation (days 3 and 4) of CD4+ T cells in the absence of exogenous cytokines. IL-4 was detected in cultures of differentiating JNK2-deficient CD4+ T cells (FIG. 4 b). In contrast, the JNK2-deficient CD4+ T cells produced lower levels of IFN-gamma compared with NOD CD4+ T cells (FIG. 4 c). Together, these data indicate that JNK2-deficiency caused an intrinsic polarization of NOD CD4+ T cells towards Th2 effectors independently of the cytokine environment. Control studies demonstrated that the Th1/2 polarization of CD4+ T cells from JNK1-deficient (Mapk8−/−) NOD mice was similar to wild-type NOD mice, indicating a selective role for JNK2 in the regulation of CD4+ T differentiation in NOD mice.

Total CD4+ cells were isolated from spleen and lymph nodes by negative selection using anti-NK1.1 (Pharmigen), anti-CD8 (TB105), anti-Macl (Pharmingen), and anti-MHC class II (m5/115) mAbs followed by depletion with magnetic beads. CD4+ T cells were activated (106 cells/ml) with immobilized anti-CD3 mAb (2C11) (5 μg/ml) and anti-CD28 mAb (Pharmingen) (1 μg/ml) in the presence of medium (for Th0 cells), IL-4 (for Th2 cells) (R&D) (103 U/ml) or IL-12 (for Th1 cells) (Genetics Institute) (3.5 ng/ml) for four days. Cells were then extensively washed, counted and equal number of cells were restimulated with immobilized anti-CD3 mAb for 24 h when supernatant was harvested. Cytokine production was determine by ELISAs using anti-IL4 or anti-IFN-γ mAb (2 μg/ml), biotinylated anti-IL4 or anti-IFN-γ mAb (1 μg/ml) (Pharmingen), horseradish peroxidase conjugated avidin D (Sigma), peroxidase substrate and reaction stop solutions

Example 6

We also tested whether the resistance of JNK2-deficient NOD mice to insulitis was exclusively due to the Th2 phenotype of CD4+ T cells or whether JNK2 could also contribute to islet β cell death. Adoptive transfer of T cells isolated from diabetic NOD donor mice causes rapid development of diabetes in sub-lethally irradiated NOD host mice within 2 to 4 weeks. We therefore transferred splenocytes from recently diagnosed diabetic female NOD mice into irradiated male NOD and NOD/Mapk9−/− mice. The frequency of diabetes caused by the T cells isolated from diabetic NOD mice was significantly reduced when these cells were introduced into JNK2-deficient NOD mice compared to control NOD mice (FIG. 3 b). The JNK2-deficient NOD group of recipient mice exhibited reduced diabetes compared with the control group of NOD mice after 8 weeks. These data suggest that JNK2-deficiency may also increase resistance of β cells to apoptosis. Although NOD/Mapk9−/− beta cells and NOD beta cells were found to be equally sensitive to apoptosis induced by IL-1beta, TNF-alpha, and IFN-gamma in vitro, it is possible that JNK2-deficiency might enhance resistance to death induced by other T cell mediators, including perforin, granzyme, or Fas ligand.
